The Characteristic of Vehicle Speed Under Angry Driving in China

摘要

Angry driving has become a serious social problem affecting traffic safety. The vehicle speed under angry driving is different from that of normal driving. However, the characteristic of vehicle speed under angry driving is not clear. To elucidate the mechanism of vehicle speed, nine participants were recruited to carry out experiment using driving simulator. The results show that the means, standard deviations, maximums, and ranges of vehicle speed in anger driving are significantly greater than those in normal driving respectively. Independent samples t-test for equality of means verify that the mean of vehicle speed in anger driving is unequal to it in normal driving. The maximums of amplitude in three-dimensional time-frequency-amplitude system for vehicle speed were extracted. The time-frequency features of vehicle speed reveal that the maximums of amplitude in angry driving are significantly greater than that in normal driving.
